1SFA611610R2110 ABB MCB-01BG 1 NC Gold-Plated Contact Block

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.

Reliable Gold-Plated Normally Closed Switching

Contact blocks convert mechanical movement from an associated control device into electrical switching within machinery and automation circuits. The ABB MCB-01BG provides one normally closed contact, maintaining electrical continuity in its normal state and changing state when the block is mechanically actuated.

The gold-plated contact surface supports dependable switching in low-level control and signalling circuits, while the compact rear-mounted format helps minimise panel-space requirements. With industrial insulation ratings, IP20 terminal protection and a mechanical durability of 10 million operations, the MCB-01BG is designed for reliable integration into industrial control systems.

Typical Applications

• Industrial pilot-device control circuits.
• Low-level signalling and monitoring circuits.
• Machine-control panels.
• Industrial operator stations.
• Interlocking and control logic circuits.
• Production and packaging machinery.
• Material handling and conveyor controls.
