Bistable relay, 16A, 2 normally closed contacts PB402 412412

Bistable relay for lighting and pulse circuit control

This bistable relay from the PB400 series is a reliable solution for switching on and off lighting circuits, as well as for pulse and manual control. Its design allows for mounting on a standard DIN rail, making installation in electrical panels easier. This relay is particularly useful in applications requiring state maintenance (on/off) without the need to continuously maintain the control voltage.

Characteristics and application

The PB402 relay is characterized by two changeover contacts (2z), making it ideal for applications where switching two independent circuits is required. The rated switching current of 16A allows it to handle most standard lighting and electrical loads. A width of 1 module ensures compact dimensions, optimizing space utilization in distribution boards. The control voltage of 230V AC (range 210-250V) is standard in most electrical installations, simplifying integration with existing control systems.

• Lighting control: ideal for switching lights on and off in residential, commercial and industrial premises.
• Pulse control: enables remote control of devices via short voltage pulses.
• Building automation: can be integrated with building automation systems to create intelligent lighting scenes and control devices.
• Industrial applications: suitable for controlling various electrical devices in an industrial environment.

Construction and operating parameters

The relay is designed for durability and reliability. Its housing is made of high-quality materials, providing resistance to mechanical damage and environmental conditions. The operating temperature ranges from -25°C to +70°C, allowing it to be used in a wide range of temperatures. The connection wire cross-section of 1x4 mm² / 2x2.5 mm² (solid/stranded) ensures a safe and stable electrical connection. The protection degree IP20 protects against finger contact and the ingress of solid objects larger than 12.5 mm. The ability to mount in any position facilitates installation in various configurations of distribution boards. The supply voltage is in the range of 0-250V AC and the control voltage frequency is 50-60Hz.
