Surge Protective Device 63A Din Rail Voltage Surge Protector 230V Adjustable Voltage Surgector Relay With Limit Current Protection Overview A DIN rail mounted surge protective device rated for 63A and designed for 230V systems. Provides adjustable voltage protection plus a relay output and built in limit current protection to reduce the impact of transient overvoltage and limit fault currents. Intended for installation in distribution boards and control panels to protect downstream equipment and reduce downtime. Key benefits Protects equipment from transient overvoltage by disconnecting or signaling when voltage exceeds the adjustable threshold. Limits fault and inrush current to reduce stress on wiring and connected devices, improving system reliability. Relay output enables remote signaling or integration with control and monitoring systems for automatic responses. DIN rail mounting and 63A rating make the unit compatible with typical industrial and commercial distribution panels. Adjustable voltage setting allows tailoring of protection to specific system tolerances without replacing hardware. Features and specifications Function: voltage surge protection with adjustable trip threshold, relay output for status or control, and built in limit current protection. Current rating: 63A. Nominal voltage: 230V. Mounting: standard DIN rail. Integration: relay contact suitable for remote alarm or control circuits. Operation: adjustable set point for surge activation to accommodate different load and system requirements. Typical use scenarios Industrial control panel: Protect PLCs, contactors, and sensors in a manufacturing control cabinet from voltage spikes and limit fault currents to downstream circuits. Commercial distribution board: Install in building main distribution to provide adjustable surge protection and remote status signaling for facility management systems. Renewable energy or inverter installations: Provide surge and current limiting protection between inverters and distribution equipment to reduce nuisance trips and protect sensitive electronics. Installation and compatibility notes Designed for DIN rail mounting in standard switchgear and distribution enclosures. Suitable for 230V single phase installations with a maximum continuous current rating of 63A. Relay contacts provide a simple interface for alarm panels, PLC inputs, or automated shutdown sequences. Performance and maintenance Adjustable voltage setting allows optimization for application needs without hardware change. Limit current protection reduces thermal and mechanical stress on wiring and connected devices during fault conditions. Periodic inspection and testing of relay signaling and connection integrity is recommended for reliable long term operation. This device is intended to enhance protection and monitorability of electrical installations where 230V DIN rail mounted surge protection with current limiting and relay signaling is required.
