Understanding IEC 60269 Fuse System E and ABB Pattern Fuse-Links

What is IEC 60269 Fuse System E? IEC 60269-2 defines several fuse systems for industrial applications. IEC 60269 Fuse System E refers to the NH (Niederspannungs-Hochleistungs) type fuse system — the blade-contact, knife-edge HRC fuse system used in NH fuse bases, switches, and distribution equipment throughout Europe and worldwide. The Lawson Type ABB 60269 Fuse is dimensionally equivalent to NH sizes 00 and 3, allowing it to be used as a BS88 Fuse equivalent in ABB Slimline Fuse-Units and other NH-envelope compatible industrial fusegear.

ABB Slimline Fuse-Units ABB Slimline Fuse-Units are a compact, modular DIN-rail or panel-mount fuse distribution system that uses blade-contact fuse-links in NH-envelope formats. The Lawson Type ABB IEC 60269-2 Fuse range provides a Lawson-manufactured BS88-2 Fuse specifically engineered to the dimensional requirements of ABB Slimline units — ensuring correct fitment, reliable contact, and certified electrical performance within this widely-used fusegear system.

Applications

The Lawson Type ABB IEC 60269-2 Fuse, BS88 Fuse, and BS Bolted Type Fuse range is specified in:

• ABB Slimline Fuse-Units — the primary application for the Type ABB, providing certified Lawson replacement and OEM fuse-links
• Industrial motor control centres (MCCs) — sub-circuit and feeder fusing within ABB pattern modular distribution equipment
• Industrial distribution boards and switchgear — NH-envelope compatible distribution fusegear at 400/415V
• Commercial and industrial building services — modular fuse distribution in building services switchrooms
• Panel builders and OEM switchgear manufacturers — specifying IEC 60269-2 Fuse links for ABB Slimline compatible assemblies
• Maintenance and replacement — like-for-like replacement of existing ABB pattern fuse-links in service

Why Choose Lawson Type ABB?

When maintaining or specifying IEC 60269-2 Fuse links for ABB Slimline Fuse-Units, it is essential to use fuse-links that are dimensionally correct for the unit and certified to the full performance requirements of IEC 60269-2 and BS 88-2. The Lawson Type ABB BS88 Fuse is manufactured to the same envelope dimensions as NH Size 00 and NH Size 3 fuse-links, ensuring correct physical fitment, secure contact engagement, and reliable arc interruption performance within ABB Slimline fuse systems.

Backed by Lawson’s decades of HRC fuse engineering expertise, ASTA Certification to the ASTA 20 Scheme, ISO 9001 accredited manufacturing, and ISO/IEC 17025 accredited test facilities, the Type ABB 60269 Fuse provides the performance assurance and traceability that industrial engineers, maintenance teams, and panel builders require from a certified BS88-2 Fuse for demanding industrial electrical installations.

Q1. What is an IEC 60269-2 Fuse?

An IEC 60269-2 Fuse is a low-voltage HRC fuse-link that complies with IEC 60269-2 — the part of the international IEC 60269 standard that covers fuses for industrial and similar applications. IEC 60269-2 specifies the performance requirements, dimensional characteristics, breaking capacities, and utilisation categories (including gG, gM, aM, and others) for industrial fuse-links across a wide range of voltages and current ratings. The Lawson Type ABB is an IEC 60269-2 Fuse in ABB Slimline pattern (NH Size 00 and Size 3 envelopes), available from 10A to 630A at 400/415V a.c.

Q2. What is a BS88 Fuse and a BS88-2 Fuse?

A BS88 Fuse is a fuse-link manufactured to comply with the BS 88 British Standard for low-voltage HRC fuses — the UK national standard that aligns with IEC 60269. BS88-2 specifically covers industrial fuse-links for general applications. A BS88-2 Fuse therefore refers to an industrial HRC fuse-link meeting the dimensional, performance, and breaking capacity requirements of BS 88-2 — including the BS Bolted Type and NH-envelope variants. The Lawson Type ABB is a certified BS88 Fuse and BS88-2 Fuse manufactured for use in ABB Slimline Fuse-Units.

Q3. What is IEC 60269 Fuse System E?

IEC 60269 Fuse System E refers to the NH (Niederspannungs-Hochleistungs) fuse system defined within IEC 60269-2, which uses blade-contact HRC fuse-links in standardised NH size envelopes (Size 000, 00, 0, 1, 2, 3, and 4). The Type ABB 00T has the same physical envelope as NH Size 00, and the 3T has the same envelope as NH Size 3 — making both Type ABB variants IEC 60269 Fuse System E compatible and suitable for use in NH-envelope fuse equipment including ABB Slimline Fuse-Units.

Q4. What is the difference between the 00T and 3T formats?

The 00T Type ABB IEC 60269-2 Fuse has the same physical envelope as an NH Size 00 fuse-link and is available in current ratings from 10A to 200A — covering sub-circuit and branch circuit protection in ABB Slimline Fuse-Units. The 3T Type ABB BS88 Fuse has the same envelope as an NH Size 3 fuse-link and is available in current ratings of 450A, 500A, 560A, and 630A — for high-current main distribution and incomer fusing applications. The two formats are dimensionally distinct and must be matched to the corresponding ABB Slimline unit size.

Q5. Can Lawson Type ABB fuse-links be used in ABB Slimline Fuse-Units as direct replacements?

Yes. The Lawson Type ABB IEC 60269-2 Fuse is specifically designed to be dimensionally compatible with ABB Slimline Fuse-Units, with the 00T format matching the NH Size 00 envelope and the 3T matching the NH Size 3 envelope. As a certified BS88-2 Fuse and IEC 60269 Fuse, the Type ABB meets the performance requirements of IEC 60269-2 and BS 88-2, making it a fully compliant like-for-like replacement for existing ABB pattern fuse-links.

Q6. What breaking capacity does the Lawson Type ABB BS Bolted Type Fuse have?

The Lawson Type ABB 60269 Fuse and BS88 Fuse range has an 80kA a.c. breaking capacity at 415V a.c. — consistent with the full performance requirements of IEC 60269-2 and BS 88-2 for industrial HRC fuse-links. This breaking capacity is suitable for the demanding fault levels encountered in industrial distribution and motor control applications.

Q7. What voltage is the Type ABB IEC 60269-2 Fuse rated for?

The Lawson Type ABB BS88-2 Fuse is rated at 400/415V a.c. — suitable for use in three-phase industrial and commercial electrical installations on standard UK and European supply voltages. It is designed for use in AC distribution systems and is not rated for DC applications.

Q8. What current ratings are available for the Type ABB BS88 Fuse?

The 00T format IEC 60269-2 Fuse is available in 13 current ratings: 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, 100A, 125A, 160A, and 200A. The 3T format is available in four high-current ratings: 450A, 500A, 560A, and 630A. Together, these cover the full current range required for ABB Slimline Fuse-Unit applications from sub-circuit through to main incomer protection.

Q9. Is the Lawson Type ABB fuse ASTA Certified?

Yes. The Lawson Type ABB IEC 60269 Fuse is ASTA Certified in compliance with the ASTA 20 Authorisation Scheme for low-voltage fuse-links. Lawson Fuses’ manufacturing operations are independently accredited to ISO 9001 and its test facilities are accredited to ISO/IEC 17025 — providing full traceability and certified performance documentation for every BS88 Fuse and 60269 Fuse supplied.
