Overview
The ABB MCB-10 is a single-pole modular contact block designed for pilot-duty control applications in industrial automation and electrical equipment. Part of ABB’s versatile modular plastic range, the MCB-10 AC-15 contact block delivers dependable switching performance with a 1 NO (normally open) contact configuration and 600V rated insulation voltage. This non-illuminated, front-mounted contact block features silver-tipped contacts for long service life and integrates seamlessly with ABB’s MP, KP, MPET, and M2SS/M3SS series pushbuttons, selector switches, and emergency stop modules.

Typical Applications
The MCB-10 is ideal for pilot-duty control of electrical equipment including fans, pumps, compressors, and motor control circuits. Common installations include:
- MP, MP2, MP3, MP4 series modular pushbutton stations
- KP6 series operator controls
- MPET, MPEP, MPEK modular emergency stop stations
- M2SS and M3SS series selector switches
- MTS toggle switches and MJS joystick controls
- Industrial control panels and pilot circuits requiring reliable on/off or monitoring contacts
Compatibility & Replacements
The ABB MCB-10 is a direct fit for all ABB modular 22mm pushbutton, selector switch, and emergency stop devices. It is part of ABB’s modular plastic range and works with plastic enclosures or 35mm DIN-rail mounting systems. The block can be stacked with other MCB-series contact blocks (MCB-01, MCB-10B, etc.) to create multi-contact configurations. For equivalent competitors in the 1NO category, check IDEC HW-series or Sprecher+Schuh D7-series contact blocks, though ABB’s MCB series offers direct OEM compatibility advantages for existing installations. Verify base model compatibility before ordering (MP1–MP4, MPD1–MPD16, KP6, MPET3–MPET4, M2SS1–M2SS6, M3SS1–M3SS8, and others).
