Type B | B Curve | 6kA | Single Pole | 230V AC
Designed to protect domestic and light commercial circuits, Type B MCBs from FuseBox provide reliable overcurrent protection, tripping between 3 to 5 times the rated current, making them ideal for resistive loads (like lighting and sockets). Suitable for use in consumer units and distribution boards.
Type B Curve Tripping:
Trips at 3–5 times the rated current – ideal for resistive and low inrush current circuits (e.g., lighting, sockets).
Rated Breaking Capacity: 6kA
Protects installations with fault current levels up to 6,000A.
Thermal & Magnetic Protection:
Dual mechanism ensures accurate tripping for both overloads (thermal) and short circuits (magnetic).
Single-Pole Operation:
Isolates only the live conductor, suitable for single-phase installations.
Fast and Reliable Performance:
Ensures quick disconnection in fault conditions to protect wiring and appliances.
Complies with BS EN 60898-1 Standards:
Fully certified for use in domestic and light commercial systems in the UK.
Compact Modular Design:
1 module wide – ideal for use in standard consumer units.
Marked Toggle Switch:
For easy identification of circuit status (ON/OFF).
Lockable Toggle (with accessories):
Option to add lock-off devices for added safety during maintenance.
RoHS Compliant & Flame Retardant Housing:
Durable and environmentally safe build quality.
