Why Choose the IMO B4B1N06A Miniature Circuit Breaker?
The IMO B4B1N06A is a compact Miniature Circuit Breaker (MCB) designed to protect low-current electrical circuits against overload and short-circuit faults. Its integrated 1 Pole + Neutral configuration enables the simultaneous isolation of the live and neutral conductors, helping improve safety during maintenance and fault conditions.
Featuring a 6 A rated current and a B curve tripping characteristic, the B4B1N06A is particularly suitable for circuits with low inrush currents, including lighting, control equipment and general-purpose electrical loads. Its compact DIN rail mounted construction makes it suitable for distribution boards, industrial control panels and OEM electrical assemblies.
The 4.5 kA short-circuit breaking capacity provides dependable protection in appropriate commercial, domestic and light-industrial installations. Clear switching indication and straightforward terminal access help support efficient installation, inspection and circuit maintenance.
Key Advantages
- Protects electrical circuits against overload and short-circuit faults.
- 6 A rated current for low-current lighting and control circuits.
- B curve tripping characteristic suitable for loads with low starting currents.
- 1 Pole + Neutral switching isolates both live and neutral conductors.
- Compact design helps conserve space within electrical enclosures.
- Standard DIN rail mounting supports quick and convenient installation.
Key Features
- IMO B4 miniature circuit breaker range.
- 6 A rated current.
- B curve overcurrent characteristic.
- 1 Pole + Neutral (1P+N) configuration.
- 4.5 kA short-circuit breaking capacity.
- Thermal-magnetic overload and short-circuit protection.
- DIN rail mounted construction.
- Suitable for distribution boards and control panels.
Reliable Protection for Low-Current Circuits
The IMO B4B1N06A uses a thermal-magnetic operating mechanism to provide two forms of protection. The thermal element responds to sustained overload conditions, while the magnetic element rapidly disconnects the circuit when a short circuit occurs.
Its B curve characteristic is intended for circuits where starting currents are relatively low. This makes the device particularly suitable for lighting, resistive loads, control systems and other applications that do not normally produce significant inrush currents.
Typical Applications
- Commercial and domestic lighting circuits.
- Industrial control circuits.
- Building automation equipment.
- Low-power electrical loads.
- Distribution boards and consumer units.
- OEM control panels and machinery.
