Why Choose the IMO B10C4016A Miniature Circuit Breaker?
The IMO B10C4016A is a high-performance four-pole miniature circuit breaker (MCB) engineered to provide dependable overload and short-circuit protection for three-phase electrical installations. As part of the proven IMO B10 Series, it combines a compact modular design with a 16 A rated current and a 10 kA breaking capacity, making it ideal for industrial control panels, commercial distribution systems and OEM machinery.
Featuring a C curve tripping characteristic, the B10C4016A is designed for circuits with moderate inrush currents. It is particularly suitable for supplying motors, transformers, contactors, solenoid valves, pumps and automation equipment where temporary starting currents occur during normal operation.
Its thermal-magnetic operating mechanism provides dual protection by responding to prolonged overloads and rapidly disconnecting short-circuit faults. With simultaneous switching across all four poles, the breaker provides safe isolation for three-phase systems and helps protect connected equipment, cabling and electrical infrastructure.

Reliable Protection for Three-Phase Power Systems
The IMO B10C4016A combines thermal overload protection with instantaneous magnetic fault protection to provide comprehensive circuit protection. The thermal element responds to sustained overcurrent conditions, while the magnetic mechanism rapidly disconnects severe short-circuit faults before damage can occur.
Its C curve operating characteristic provides instantaneous tripping at approximately five to ten times the rated current, making it suitable for inductive loads that experience temporary starting currents. This helps reduce nuisance tripping while maintaining reliable protection for industrial electrical systems.
The mechanically linked four-pole construction ensures all conductors are disconnected simultaneously during manual isolation or automatic fault operation, improving safety when maintaining or servicing three-phase electrical equipment.
Typical Applications
- Industrial control panels.
- Three-phase distribution boards.
- Motor starter circuits.
- Automation and machinery.
- HVAC equipment.
- Pump and compressor installations.
- Commercial electrical distribution.
- OEM manufacturing equipment.
