Description
The Master Lock S2394 Universal Mini Circuit Breaker Lockout Device is designed to secure virtually all miniature ISO/DIN pin-out circuit breakers during maintenance and servicing procedures. This lockout/tagout (LOTO) device provides essential safety protection by preventing accidental re-energisation of isolated circuits, making it ideal for electricians and maintenance engineers working on electrical installations across industrial, commercial and facilities management applications. The patented design features a thumb turn dial screw for quick, tool-free attachment to the circuit breaker. Once fitted, the device blocks access to the breaker's dial in the locked position, preventing unauthorised removal or circuit reactivation. The versatile mounting system accommodates padlocks in either horizontal or vertical orientations, whilst the compact profile allows multiple devices to be installed side-by-side on adjacent breakers without obstruction. This universal lockout device is compatible with all Master Lock and American Lock safety padlocks and lockout hasps, providing flexible integration with existing LOTO systems (excluding ALO80 and ALO802 models). The robust construction ensures reliable performance across a wide range of international circuit breaker designs, making it a practical solution for organisations maintaining consistent safety standards across multiple sites. Features and Benefits: • Tool-free installation with thumb turn dial screw for fast application • Universal design fits miniature ISO/DIN pin-out circuit breakers worldwide • Side-by-side mounting capability for adjacent breaker lockout • Flexible padlock orientation for confined installation spaces • Compatible with Master Lock and American Lock safety padlocks and hasps
