The SZD1125/300010 is a 2position OFFON load break isolator designed for panel mounting in threephase electrical systems. It combines a rotary cam switch with a padlockable panel switch for safe isolation and maintenance, delivering a clear on/off control with a 25 A current rating across 3 poles. The changeover rotary cam switch design supports reliable switching in control circuits, while the padlock feature supports lockout/tagout practices to enhance safety on equipment and panels. Key benefits Safe circuit isolation for maintenance: padlock panel switch enables lockout to prevent accidental reenergizing during service work. Simple, reliable operation: twoposition OFFON action with a sturdy rotary cam mechanism for quick and clear operation. Suitable for 3phase applications: 3P configuration supports three separate conductors for balanced loads. Adequate for small to medium loads: 25 A current rating fits typical control panels and motor control circuits. Integrated changeover capability: designed as a changeover rotary cam switch for versatile circuit switching within control panels. Key attributes Functionality: OFFON, 2 positions; load break isolator; padlockable panel switch; changeover rotary cam switch. Poles and rating: 3P, 25 A. Mounting: Panelmount design suitable for integration into control enclosures and switchboards. Safety features: padlock capability to secure the OFF position and prevent accidental reenergization. Construction: Rotary cam switch mechanism engineered for dependable operation in industrial environments. Model: SZD1125/300010. Typical applications Safe maintenance of threephase motors and feeders: isolate the motor or circuit before service work and apply a padlock to ensure it remains deenergized. Control panel isolation: provide a clear OFF position for routine powerdowns and troubleshooting within electrical control panels. Panel and machine safety interlocks: use in control circuits where quick, reliable isolation and changeover operation are required to secure equipment during setup or testing. Usage tips Install in accordance with local electrical codes and manufacturer instructions. Use an appropriate padlock with a compliant hasp to lock the OFF position during maintenance. Verify that the switch is fully in the OFF position and padlocked before servicing any connected equipment.
