Product Description
RS PRO 0476577P PCB Power Relay is a durable and efficient power relay designed for switching high current loads up to 50 A. This relay features a 12V DC coil and SPST contact configuration, making it ideal for applications requiring reliable single-pole control.
The relay consumes 3 W coil power with a 48 Ω coil resistance, activated by a low-current pulse. Its silver alloy contacts guarantee excellent conductivity and longevity, rated for 1,000,000 mechanical cycles. With overall compact dimensions measuring 39 mm in length, 30.2 mm in height, and 15 mm in width, it fits neatly onto printed circuit boards using through-hole solder terminals.
Special features include a dielectric strength of 4 kV to protect against electrical interference, the capability to handle capacitor loads up to 200 μF, and lamp load capacities up to 5000 W. The relay supports a maximum switching power of 12.5 kVA AC and a maximum switching voltage of 440 V AC, suitable for heavy-duty electrical switching tasks.
It is engineered to operate over a wide temperature range from -40°C to +70°C, making it suitable for harsh industrial environments, HVAC systems, industrial counting and sorting machinery, and cleaning equipment.
Coil power: 3 W for efficient low power consumption. Coil resistance: 48 Ω. SPST silver alloy contacts provide robust electrical performance. Compact PCB mounting with dimensions 39x30.2x15 mm. Dielectric strength of 4 kV between coil and contacts for enhanced safety.
Capable of handling inrush currents with minimum surge impact. Mechanical life of up to 1,000,000 cycles ensures long-term reliability. Operating temperature range from -40°C to +70°C suits demanding environments. RoHS compliant to meet environmental standards.
Through-hole solder terminal type for secure PCB attachment.
