SZD11 25/300010 B — 25 A, 3-pole ON/OFF panel load-break isolator switch. Padlockable for safe lockout-tagout and built for reliable manual isolation in control panels and electrical cabinets. Key benefits Safe, fast isolation: Quickly de-energize circuits for maintenance or testing to reduce risk to personnel and equipment. Lockout-ready: Padlockable design supports secure lockout-tagout procedures to prevent accidental re-energization. Reliable actuation in tight spaces: Long-bar cam-operated mechanism delivers positive, consistent switching even in compact electrical cabinets. Panel-friendly footprint: Panel-mount design fits standard electrical enclosures, keeping installations tidy and accessible. Durable, simple operation: Manual ON/OFF control with construction suited to industrial control and distribution environments. Main features and specifications Model: SZD11 25/300010 B Function: ON/OFF panel load-break isolator switch Rated current: 25 A Poles: 3-pole (suitable for three-phase circuits) Mechanism: Long-bar cam-operated for positive, reliable actuation Mounting: Panel-mount design for standard electrical enclosures Safety: Padlockable for lockout-tagout compliance Application environment: Control panels and electrical cabinets; compact footprint for tight spaces Practical use scenarios Maintenance on a manufacturing line: Isolate a service panel or machine circuit to safely perform repairs or preventive maintenance using the padlockable switch. Installation or troubleshooting in a distribution board: De-energize specific circuitry in a distribution board for safe testing or component replacement. Control cabinet lockout for MCC or machine work: Provide a lockout-ready isolator in motor control centers or control cabinets during commissioning or servicing. Installation and operation notes Designed for panel mounting in standard electrical enclosures; verify cutout and mounting requirements in your panel layout. Manual ON/OFF operation with long-bar cam mechanism ensures positive switching in tight cabinet spaces. Use padlock feature to implement lockout-tagout procedures during maintenance or testing. The SZD11 25/300010 B is intended to deliver reliable isolation in panel environments and is compatible with standard three-phase systems where a 25 A, 3-pole load-break isolator is required.
