Why Choose the Mersen BTIA42V32M40 Motor-Rated Fuse-Link?
The Mersen BTIA42V32M40 is a British Standard industrial fuse-link designed to provide reliable short-circuit and overcurrent protection for motor circuits and associated electrical equipment. Its motor-rated operating characteristics allow it to withstand the temporary inrush current generated during normal motor starting while responding effectively to qualifying electrical faults.
This fuse-link is suitable for protecting motor starters, contactors, cables, switchgear and machinery within commercial and industrial installations. Its offset-tag construction provides a secure connection when installed in compatible BS88 fuse holders, fuse switches and motor control assemblies.
The product designation indicates a 32M40 motor rating and a voltage class of approximately 415 V AC. The exact utilisation category, DC rating, breaking capacity, dimensions and fuse-holder compatibility should be confirmed against current Mersen technical documentation before specification or installation.
Key Advantages
- Motor-rated fuse-link designed to accommodate normal starting currents.
- 32M40 rating for compatible industrial motor circuits.
- Suitable for low-voltage systems operating at up to approximately 415 V AC.
- Helps protect cables, contactors, motor starters and switchgear.
- Current-limiting operation helps reduce damaging fault energy.
- Offset-tag format for secure installation in compatible fuse equipment.
Key Features
- Mersen BTIA industrial fuse-link series.
- 32M40 motor circuit designation.
- 415 V AC voltage class.
- Designed for industrial motor circuit protection.
- Suitable for circuits with temporary starting-current peaks.
- Current-limiting performance during short-circuit conditions.
- Offset-tag connection arrangement.
- Non-resettable fuse element.
Reliable Protection for Industrial Motor Circuits
Electric motors can draw several times their normal operating current during start-up. A correctly selected motor-rated fuse-link is designed to tolerate this temporary inrush without unnecessary operation while still providing rapid interruption when a serious short circuit occurs.
The Mersen BTIA42V32M40 can help limit the peak current and energy passed into a fault, reducing thermal and mechanical stress on cables, contactors and other components. Overload protection may also require coordination with a suitable motor overload relay or motor protection device.
Fuse selection should account for the motor's full-load current, starting method, starting duration, duty cycle, ambient temperature and prospective short-circuit current. The selected fuse holder and switchgear must also be rated for the applicable voltage, current and fault level.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Pumps, fans and ventilation systems.
- Conveyors and material-handling equipment.
- Compressors and processing machinery.
- OEM automation and control panels.

Frequently Asked Questions
What is the Mersen BTIA42V32M40 used for?
The BTIA42V32M40 is intended for protecting industrial motor circuits, cables, contactors, starters and associated switchgear against qualifying electrical faults.
What does the 32M40 designation mean?
The 32M40 marking is a motor-circuit fuse designation. It identifies a fuse-link designed to tolerate normal motor starting current while being selected and coordinated for an appropriate motor circuit.
What voltage is the BTIA42V32M40 rated for?
The product code indicates a voltage class of approximately 415 V AC. The precise AC and DC ratings should be verified against the current Mersen data sheet.
Does this fuse replace a motor overload relay?
Not necessarily. Motor-rated fuse-links are commonly used for short-circuit protection, while a correctly selected overload relay or motor protection device provides overload and phase-loss protection.
Can the BTIA42V32M40 be reset after operation?
No. It is a non-resettable fuse-link and must be replaced with a compatible product of the correct type and rating after it operates.
Trusted Motor Circuit Protection from Mersen
Mersen industrial fuse-links are used in motor control and power distribution systems to help protect cables, starters, switchgear and machinery. Final selection should be verified using current manufacturer data and the protection requirements of the installation.
