Special relays for high industrial loads

If currents above 10 A have to be switched, standard relays are subject to high wear and quickly reach the limits of their service life. Our power switches has been specially developed to control high AC loads. They are ideally suited for motors or heating elements up to 30 A and can be used in many other power applications.

Power solid-state relays (PSSR) up to 30 A
Our solid-state contactors are far superior to mechanical contactors. They achieve higher switching speeds and are more robust and durable. They switch ohmic and inductive loads silently, wear-free and reliably – even in dusty or chemically aggressive atmospheres. Our solid-state contactors are available for 1- and 3-phase mains.

Miniature contactors (PWR) up to 30 A
Conventional contactors are oversized for some power applications in which industrial relays wear quickly and only achieve a short service life. This is where our PWR miniature contactors are used. Thanks to switching currents of up to 30 A, a double-break contact and a significantly larger contact gap, they are able to switch industrial loads reliably.

Product group overview

	Power solid-state relays PSSR single phase PSSR 3-phase	Switch high AC loads up to 30 A and DC loads up to 15 A completely wear-free, reliable and noiseless Due to their high shock and vibration resistance, the large switching current and the option of simple fusing, our power solid-state relays outperform by far any electromagnetic relays, especially in the process industry. The compact modules have low power drive requirements, fast response times and operate noiseless. The version with integrated current monitoring allows the switching current monitoring of up to five parallel connected loads. Our new power solid-state relays are ideally suited for a multitude of diverse tasks: switching of pipe heaters and infrared heaters, or permanent current monitoring. Compact design with a width from 17.8 mm Switching currents of up to 30 A and up to 15 A DC High shock and vibration resistance Ready to use with integrated heat sink and mounting rail base for mounting on DIN rail TS35 Short circuit protection with circuit breakers possible Output connections ring lug suitable

	Electromechanical relays PWR - 1 NO contact PWR - 2 NO contacts	Our small industrial contactors of the PWR are particularly suitable for switching larger load currents. 1 NO contact (30 A) and 2 NO contacts (25 A) AgSnO Contact material Double contact to increase contact opening Direct mounting on DIN rail TS35 With integrated status LED
