Raychem T-M-20-S/+x+y/EX mechanical thermostat

Prezentare generală

The Raychem T-M-20-S is a surface sensing thermostat providing temperature control and a temperature limiter for non-hazardous areas.

The high limit cut out prevents the heating system exceeding a preset maximum temperature should the control function fail to operate or an unsafe process temperature occur. Temperature set point adjustment and limiter reset can be completed, without opening the enclosure, via removable plugs in the lid. The thermostat is available in 3 temperature ranges. 0°C-50°C; 0°C-200°C; 50°C-300°C.

The Raychem T-M-20-S/+x+y/EX surface sensing thermostat provides temperature control and a temperature limiter for in hazardous areas.

The high limit cut-out prevents the heating system exceeding a preset maximum temperature should the control function fail to operate or an unsafe process temperature occur. The maximum rated voltage is 400 VAC. The switching current capacity is 16 Amp maximum. The thermostat is available in 2 versions:

1. Thermostat +0C to +200C, Limiter =+50C to +300C
2. Thermostat +50C to +300C, Limiter =+50C to +300C
