Emergency Stop Switches / E-Stop Switches ESTOP 40MM PULL RELEASE RED 2NC
Research Notes
1. What this is
MPEP4-20R-02 is a ABB MP/CP 22mm command switch.
2. Part-number decode
- Series: ABB Modular MP/CP
- Type: command switch
- Panel cutout: 22mm
3. Compatibility & ordering
ABB makes Modular (MP metal / CP plastic) 22mm command switches, CE compact switches, KP mushroom operators, and Jokab (2TLA) safety products. Match by type, actuation, illumination, sealing, and mounting, then use the manufacturer datasheet to confirm the exact contact and termination encoded in the part number.
4. Data-quality note
The ABB series and switch type are decoded from the part number (grounded in the manufacturer catalog and distributor listings). The exact contact arrangement, termination, and cap/colour are encoded in the full order code — confirm against the datasheet for a precise order (not guessed here).

Referência rápida de instalação
Panel cutout: 22mm. Mount with the yellow backing plate visible (required by EN/ISO 13850).
Wiring: Wire NC contacts in series with the safety relay input channels. Use dual-channel wiring for SIL 3 / PLe applications. Never wire directly to a motor contactor.
Testing: Press the e-stop and verify the machine stops within the required time. Test the reset mechanism. Repeat monthly per EN/ISO 13850.

Solução de problemas
E-stop won't reset (twist/pull doesn't release)
Check for debris in the mechanism. For twist-release: turn clockwise 45-90 degrees. For push-pull: pull straight out firmly. If the mechanism is stuck, the internal latch may be damaged — replace the entire head assembly.
Machine doesn't stop when e-stop is pressed
Critical safety issue. Immediately lock out the machine. Check wiring — NC contacts must be in series with the safety relay. Verify the safety relay is functioning. A broken wire in an NC circuit should cause a stop, so check for a wiring bypass.
Safety relay faults after e-stop reset
The safety relay detects a cross-fault between the two monitoring channels. Check that both NC contacts on the e-stop are switching simultaneously. One contact may be welded closed — replace the contact block.
