Monitoring relay RPN-1A5-A230 864367

Single-phase current monitoring – RPN-1A5-A230 relay

The RPN-1A5-A230 supervisory relay is a reliable device designed to monitor current in single-phase circuits. Designed by RELPOL, it works well in both industrial applications and building installations where ensuring safety and continuity of operation is crucial. Its compact dimensions and DIN rail mounting simplify integration with existing automation systems.

Functionality and application

The device is used to monitor the current value in the range of 0…5A, reacting to exceeding or falling below defined thresholds. This makes it possible to detect failures, overloads or malfunction of connected devices. The relay has one changeover contact, which can be used for alarm signaling, load disconnection or activation of other protective functions. This is a versatile solution for installers and users looking for an effective way to protect their electrical installations.

• Current monitoring: Control of the current value in a 1-phase circuit.
• Alarm signaling: Informing about exceeding or falling below defined current thresholds using a changeover contact.
• Overload protection: Possibility of disconnecting the load in case of detecting a dangerous condition.
• DIN rail mounting: Quick and easy mounting in electrical panels.
• Wide operating temperature range: Trouble-free operation in difficult environmental conditions (-20…60°C).

Technical characteristics and construction

The RPN-1A5-A230 relay is characterized by a supply voltage of 230V AC (50/60Hz) and the ability to operate in a wide range of ambient temperatures. Made of high-quality materials, it ensures long-lasting and reliable operation. Screw terminals allow for solid connection of wires, and the IP20 degree of protection provides protection against touch and small solid particles. Compact dimensions (17.5x90x64.6mm) allow installation even in limited space. The SPDT output (changeover contact) offers flexibility in configuring control and protection circuits. The applied solution allows for quick reaction to current changes – the contact operating delay can be adjusted in the range of 0.5…20s, allowing you to adapt the relay's operation to the specifics of the protected installation.
