Installation relays E297 are electromagnetically actuated small contactors with a width of 18mm (1 module unit). With these installation relays a reliable consumer control can be designed. As a rule, the installation relays are used via a control switch (permanent contact) where, for example, lighting, air conditioning, a fan or similar is to be controlled. The device remains in the on position as long as the control voltage is applied to the coil. If the control voltage is interrupted, the installation relay always falls back to the rest position (off position). Thanks to the optimum switching capacity, they are also suitable for applications in industrial environments and in situations where it is necessary to ensure control over more powerful consumers (such as several lighting groups). The use of an optimized coil (low power loss = lower operating temperature) ensures trouble-free and safe use in the electrical distributor. The quiet switching noise and the hum-free magnetic system also justify use in public buildings and in private households. Depending on the type, the installation relays can be controlled with common AC/DC control voltages and are designed for a rated current of 16 A.
