Detailed Product Description

Miniature Circuit Breaker KB

• Pin/ Fork type busbars: KB-6 series MCBs can be connected through pin type & Fork type busbars. Bottom terminal for Fork type busbar is isolated between the poles.
• Energy Saver: The Watt loss of the MCBs is extremely low providing valuable savings over its entire lifecycle.
• Mounting: The two-position DIN clip facilitates easy mounting and removal from the DIN channel.
• Accessories: Flexible modular accessories like Shunttrip, Motor mechanism, Undervoltage release and Auxiliary contacts.
• Trip Free Mechanism: The MCB trips positively even when it’s locked in on (I) position.
• Double Terminal Design: Double function terminal design for connecting both busbar and conductors at the same time.
• Interrupting Capacity: KB-6 series MCBs provide 6kA & 10kA breaking capacity. They operate on current limiting principle ensuring extremely low let through energy (I2t) under fault conditions.
• IP20 Safety Protection: Touch proof terminals ensure maximum operator safety against accidental contact.
