⚡ Key Features

25 A rated current — provides overload and short-circuit protection for the connected circuit.
Curve B tripping characteristic — optimised for cable and resistive loads (lighting, heating, socket circuits) — trips magnetically at 3–5× rated current.
1 Pole — protects a single-phase final circuit; fits standard 35mm DIN rail in distribution boards.
Thermal-magnetic trip mechanism — bimetal element trips on sustained overload, instantaneous magnetic trip on short-circuit; two independent protection functions in one compact module.
Manufactured to IS 8828 / IEC 60898-1 (residential) and IEC 60947-2 (industrial) — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified where applicable — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Leading Brand product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.

❓ Frequently Asked Questions

Q: What load can the DHMGBSPF025 protect at its rated 25 A?

A: The DHMGBSPF025 is rated to carry and protect circuits up to 25 A continuously. For motor loads, ensure the full-load current (FLC) of the motor does not exceed this rating. For resistive loads (heaters, lighting), the 25 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: Why is Curve B specified for the DHMGBSPF025 and what loads is it optimised for?

A: Curve B on the DHMGBSPF025 trips magnetically at 3–5× rated current, making it ideal for resistive loads such as incandescent lighting, electric heaters, and PTC elements. Using the wrong curve can cause nuisance tripping (too sensitive) or inadequate protection (not sensitive enough). Always match the curve to the load’s inrush characteristics.

Q: Can the DHMGBSPF025 be DIN rail mounted in any standard distribution board?

A: Yes. This Leading Brand MCB uses the standard 35mm EN 60715 DIN rail and 17.5mm module width, making it compatible with all major brand distribution boards and enclosures. Terminal capacity accommodates both rigid and flexible conductors up to the rated cross-section.

Q: What happens when the DHMGBSPF025 trips — how do I identify and reset it?

A: When the DHMGBSPF025 trips on fault, the handle moves to a midway position (between ON and OFF), distinctly visible from a distance. To reset: (1) identify and rectify the fault, (2) push the handle fully to OFF, (3) then switch back to ON. Never force-reset without investigating the fault cause.

Q: Is the DHMGBSPF025 suitable for both single-phase and three-phase systems?

A: The DHMGBSPF025 is a 1 pole device for single-phase circuits. For three-phase circuits, use a 3-pole or 4-pole MCB of the same series.
