Eaton Z-SLZ/SP Switch-on Interlock, Padlockable, for PKZ0/PKE/NZM Series 268981

The Eaton Z-SLZ/SP is a mechanical switch-on interlock that prevents unauthorized or accidental activation of circuit breakers and motor protective circuit breakers. Unlike generic lockout tags that only warn, this device physically blocks the operating mechanism, making it a reliable component for Lockout/Tagout (LOTO) procedures in industrial environments.

Highlights

• Padlockable design accepts up to 3 padlocks with shackle diameters from 4 to 8 mm.
• Compatible with Eaton PKZ0, PKE, and NZM series (NZM1–NZM4) circuit breakers.
• Constructed from high-quality thermoplastic in red and black for high visibility.
• Front mounting on the operating mechanism for straightforward installation.
• Operating temperature range: -25°C to +70°C.

In daily use

During maintenance or repair, the interlock is fitted onto the breaker's front operating mechanism. Once padlocks are inserted, the breaker cannot be switched on until all locks are removed, ensuring compliance with safety protocols and protecting personnel from unexpected energization.
