Why Choose the ABB MCB-01BG Contact Block?
The ABB MCB-01BG is a modular single normally closed (1 NC) contact block with gold-plated contacts designed for industrial pilot-device, signalling and control applications. Part of the ABB Modular pilot device range, it provides dependable switching where a normally closed circuit and reliable low-level contact performance are required.
The MCB-01BG features a 1 NC contact configuration, meaning the electrical circuit is closed in its normal, unactuated state and changes state when the block is mechanically operated. Its gold-plated contact surface makes the contact block particularly suitable for low-level switching and signalling duties where consistent electrical contact is important.
Designed for rear mounting, the MCB-01BG combines compact dimensions with industrial electrical ratings including a 690 V rated insulation voltage and 6 kV rated impulse withstand voltage. IP20 terminal protection, a wide operating temperature range and a mechanical durability of 10 million operations support dependable service in industrial machinery and automation installations.
