The BTBC42V63 fuse-link provides reliable circuit protection at 415VAC and 240VDC up to 63A with a gG characteristic for overload and short-circuit defence in industrial and commercial installations.
£7.35
The Mersen BTBC42V63 is a high-quality BS88 gG central bolted-tag fuse link designed to protect low-voltage electrical circuits against overloads and short circuits. Manufactured by Mersen, it provides dependable fault interruption for cables, conductors, switchgear and connected equipment in industrial and commercial power distribution systems.
As part of Mersen’s central bolted-tag fuse-link range, the BTBC42V63 combines full-range circuit protection with effective current-limiting performance. Its gG utilisation category enables it to protect electrical installations against sustained overload currents and high-level short circuits, helping to reduce thermal and mechanical stress on downstream components.
With a rated current of 63 A, an AC voltage rating of up to 415 V and a DC voltage rating of up to 240 V, the BTBC42V63 is suitable for switchboards, distribution panels, machinery and feeder circuits. Its central bolted-tag configuration provides a secure electrical and mechanical connection within compatible fuse holders and fused switching equipment.
The Mersen BTBC42V63 is designed to disconnect an electrical circuit when current rises beyond safe operating limits. Its gG characteristic provides full-range protection, covering prolonged overload conditions and high-level short circuits that could otherwise damage cables, switchgear and connected electrical equipment.
During a serious fault, the fuse limits the peak current and total electrical energy passing through the circuit. Correct coordination with the associated fuse holder, switching device and downstream equipment can help reduce thermal and mechanical stress, improve installation safety and minimise unplanned operational downtime.
