Description

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.

Key Features

  • 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.
