Model W2R4P220V — Transfer Switch, 4P 25A Overview The W2R4P220V transfer switch provides reliable switching between power sources for 220V electrical systems. Its fourpole 25A configuration handles threephase plus neutral switching where full circuit isolation or source selection is required. Key benefits Reliable source transfer: Enables a clean changeover between primary and backup power to minimize downtime and maintain continuous operation. Full fourpole switching: Switches three phases and neutral together for proper isolation and balanced load handling in threephase installations. Clear rating for planning: Marked as 4P 25A and W2R4P220V for straightforward selection and load matching when designing or upgrading electrical systems. Stable electrical connection: Designed for repeated switching operations in common industrial and commercial applications. Function and compatibility Function: Manual or panelmounted transfer of electrical supply between two power sources for a 220V system using a fourpole switching arrangement. Compatibility: Intended for 220V systems that require fourpole transfer capability and for circuits specified at 25A. Suitable for installations where threephase lines and neutral must be switched together. Important attributes Model: W2R4P220V Configuration: 4P 25A (four poles, 25 ampere rating) Voltage: 220V system compatibility Application focus: Source transfer and circuit isolation in electrical distribution setups Practical use scenarios Backup generator integration: Use the W2R4P220V to switch critical loads from utility power to a backup generator in small commercial buildings or facilities with threephase supply and neutral. Maintenance and testing: Isolate and switch circuits during maintenance on distribution panels or when testing alternate power sources without affecting other parts of the installation. Equipment and motor control: Provide controlled transfer for threephase equipment that requires neutral switching along with phase conductors to prevent unbalanced conditions. Installation and operation notes Select the W2R4P220V when the circuit design specifies fourpole transfer and a 25A rating at 220V. Installation should follow local electrical codes and be performed by a qualified electrician to ensure correct wiring and secure connections. This transfer switch is a straightforward solution for systems that require dependable fourpole switching at a 25A rating for 220V installations.
