SIEMENS 3TH2040-0AK6 Contactor Relays 4 NO 120VAC

SIEMENS 3TH2040-0AK6 contactor relays are switching devices for control and auxiliary circuits and are used for controlling, signaling and locking switching devices and switchgear. Naturally, SIRIUS contactor relays come with standard-compliant connection designations and a connection system that saves both time and installation overhead. This makes them particularly suitable for practical applications. SIEMENS contactor relays and size S00 motor contactors are the same size and have an identical design - a significant advantage, particularly with regard to the accessories. They are designed for AC or DC operation and are available with screw or spring-loaded terminals. The basic version of the contactor relays is a 4‑pole design which can be extended up to eight poles by means of snap-on auxiliary switches.
