Fuses

Bolt-in BS88 Type T Fuses (British & IEC Fuses)

The RS (Red Spot) Type T range forms the foundation of IPD's HRC fuse offering. Certified to BS88 Part 2:1988, IEC 60269-2 and AS 2005.21.2, these ASTA 20-certified fuse links provide fault protection up to 80kA from 415V to 660V, with DC performance up to 460V.

Available in both gG (general purpose, full range) and gM (motor circuit) classifications. The full Type T family ranges from 2A to 1250A across multiple frame sizes: 

Type T fuse links provide ASTA-certified Type 2 coordination with motor starters in accordance with IEC 60947-4-1 when paired with suitable contactors and overload relays. The gM classifications allow economical motor circuit protection by enabling larger starting current characteristics without increasing fuse holder size.

Safeclip BS88 Clip-In Fuses

IPD's Safeclip range provides convenient clip-in fuse solutions certified to BS88 Part 1 or Part 6:1988 and IEC 60269-1.

The range includes:

• SS series: 2 – 20A at 240V AC, 16.5kA breaking 
• NS series: 2 – 32M40A at 415V AC, 80kA breaking 
• ES series: 40 – 63M80A at 440V AC (415V for 63M80), 80kA breaking

Safeclip fuses offer discrimination ratios of 2:1 between Safeclip ratings, or 1.6:1 when used downstream of RS Type T fuse links. They are widely used in industrial, utility and distribution installations where fast fuse replacement is important.

J-Type Utility Fuses

Class L Power Fuses (Mersen Amp-trap 2000 A4BQ) 

The Mersen Amp-trap 2000 A4BQ Class L range provides high-current protection for service entrances, mains, feeders, large motors and circuit breaker back-up applications. The specifications include: 

• AC: 100 – 6000A at 600V AC, 200kA IR (self-certified to 300kA, UL witnessed) 
• DC: 601 – 3000A at 500V DC, 100kA IR 
• 4-second time delay at 500% rating — accommodates inrush from large motors and transformers 
• UL Listed (601 – 6000A) to UL 248-10, CSA Certified to C22.2 No. 248.10, IEC 60269-2-1 
• Pure silver fuse elements, fibreglass body, high-grade silica filler 
• Rejection-style design prevents replacement errors 
• Applications: mains, feeders, large motors, lighting/heating, circuit breaker back-up, UPS DC links, battery disconnects 

Important product for big switchboard mains and CB back-up — typically specified as the upstream device behind a low-IR breaker to series-rate up to 200kA+.

Semiconductor Fuses (Mersen — BS88 Part 4) 

IPD supplies Mersen semiconductor fuses designed to protect sensitive power electronics including VSDs, soft starters, UPS rectifiers, thyristors and IGBT equipment. The comprehensive size range is: 

Available with separate trip-indicator microswitches (MC 6.3 GR 2-5N, MC 36 GR 2-5) for remote blown-fuse signalling — useful in VSD and UPS panels where fuse-blown alarms feed back to a PLC or SCADA system. Selection between aR and gR classes matters: gR class clears all overloads from low multiples to short-circuit currents, enabling protection of cables without additional components and selective coordination with upstream gG fuses. aR class only handles short-circuit currents and requires backup overload protection. 

Photovoltaic (PV) Fuses

IPD's photovoltaic fuse range provides dedicated DC protection for solar string and array installations. The specifications are: 

• Mersen HP10M series: 10x38mm gPV ferrule, 1000V DC
