Why Choose the Mersen BNS55V16M20 Motor Protection Fuse Link?
The Mersen BNS55V16M20 is a compact British Standard motor protection fuse link designed to provide dependable short-circuit protection for industrial motors, motor starters and associated control equipment. Its motor-rated operating characteristic allows it to tolerate the temporary inrush current produced during motor starting while responding rapidly to severe electrical faults.
The BNS55V16M20 provides current-limiting protection that helps reduce the thermal and mechanical energy passed through to contactors, cables, switchgear and downstream components during a short circuit. This can minimise equipment damage, support effective protection coordination and reduce disruption within industrial motor-control systems.
With a 16M20 motor rating and a nominal voltage rating of 550 V AC, this Mersen fuse link is suitable for compatible low-voltage motor circuits and machinery installations. Its bolted-tag construction provides a secure electrical connection when installed in an appropriately rated fuse holder, switch-fuse unit or motor-control assembly.
Key Advantages
- Purpose-designed short-circuit protection for industrial motor circuits.
- 16M20 motor rating accommodates normal motor-starting current.
- 550 V AC nominal voltage rating for compatible industrial systems.
- Current-limiting operation helps reduce damaging fault energy.
- Supports coordination with motor contactors and overload relays.
- Bolted-tag construction provides a secure and reliable connection.
Key Features
- Mersen British Standard motor protection fuse link.
- 16M20 motor-circuit rating.
- 550 V AC nominal operating voltage.
- Motor-rated time-current characteristic.
- Designed to withstand temporary motor-starting currents.
- Rapid interruption of high short-circuit currents.
- Current-limiting performance for improved equipment protection.
- Non-resettable design requiring replacement after operation.
Reliable Protection for Industrial Motor Circuits
Electric motors can draw several times their normal running current during start-up. A motor-rated fuse such as the Mersen BNS55V16M20 is designed to withstand this temporary inrush without unnecessary operation while still interrupting dangerous short-circuit currents quickly.
The fuse is normally used alongside a correctly selected overload relay or electronic motor protection device. The fuse provides high-level fault protection, while the overload device protects the motor against sustained overcurrent conditions. Selection should account for the motor current, starting method, starting duration, conductor capacity and prospective short-circuit current.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres and control panels.
- Pumps, fans and ventilation systems.
- Conveyors and material-handling equipment.
- Compressors and production machinery.
- Fuse-switch and industrial distribution assemblies.
