MCAH10 IMO Auxiliary Contact Block High Switching Capacity 25A AC1, 1

Why Choose the IMO MCAH10 Auxiliary Contact Block?

The IMO MCAH10 is a compact, high-capacity auxiliary contact block designed to expand the control and signalling capabilities of compatible IMO contactors. Featuring 1 normally open (1NO) contact, it provides dependable status feedback, electrical interlocking and supplementary switching for industrial automation and motor-control circuits.

Designed for convenient top mounting, the MCAH10 connects directly to compatible IMO MC contactors without requiring a separate mounting assembly. Its mechanically operated contact changes state with the contactor, allowing reliable monitoring, sequencing and control of associated electrical equipment.

With a high switching capacity of 25 A for AC-1 loads, the MCAH10 is suitable for demanding auxiliary circuits where a standard low-current contact block may not provide sufficient capacity. Its compact design helps conserve panel space while providing dependable switching for industrial machinery, control panels and OEM systems.

Key Advantages

• Compact high-capacity auxiliary contact block.
• 1 normally open contact for feedback and control circuits.
• 25 A AC-1 current rating.
• Direct top mounting onto compatible IMO contactors.
• Provides supplementary switching without requiring a separate relay.
• Supports electrical interlocking, sequencing and signalling functions.
• Designed for industrial automation and motor-control panels.

Key Features

• IMO high-capacity auxiliary contact range.
• 1NO contact configuration.
• 25 A AC-1 switching capacity.
• Top-mounted contactor accessory.
• Mechanically operated by the associated contactor.
• Compact construction for space-efficient control panels.
• Suitable for selected IMO MC contactor models.
• CE, cUL and UL approved design.

Reliable Auxiliary Switching for Industrial Control

Auxiliary contact blocks such as the IMO MCAH10 provide an additional contact that operates simultaneously with the main contacts of a contactor. The normally open contact closes when the contactor energises, allowing control systems to confirm operation, initiate another process or provide status feedback to a PLC.

The MCAH10 is particularly useful where a higher-capacity auxiliary contact is required. Its direct top-mounted design reduces wiring complexity and panel space while maintaining dependable mechanical coordination with the associated contactor.

Typical Applications

• Contactor status feedback circuits.
• Electrical interlocking systems.
• Motor starter control panels.
• PLC input and monitoring circuits.
• Industrial sequencing systems.
• Machine automation and OEM equipment.
