From 25 A to 75 A
Bimetal temperature limiters from 25 A to 75 A
Series H5 (with normally closed contact)
The main components of the H5 series are a silver mobile contact (1), a contact support (2), a snap-action spring disc (3), a bimetal disc (4) and a contact tongue (5) that are riveted together.
The mobile contact is pressed against the upper housing by the spring disc and the bimetal disc is free to move as the temperature increases, without it altering the pressure applied by the spring disc on the contact.
When the nominal switching temperature is reached, the bimetal disc springs back from the convex position to the concave position, overcoming the force of the spring disc and causing the contact to open immediately.
Series XO (with normally closed contact)
Suitable for currents of up to 75A
XH Series coupled with a triac.
A controllable Triac, connected in parallel with a three-pole switch, allows the arcs generated during switching processes to be suppressed.
