E-T-A's ESX10-T

E-T-A's ESX10-TE-T-A Circuit Breakers is pleased to announce the ESX10-T Electronic Circuit Protector now has CSA Approval C22.2 and Class I, Division 2 Hazardous Location Certification - Group A, B, C, and D.The hazardous location approvals will allow the ESX10-T to be used in applications such as mining, petro/chemical, pharmaceutical and food and beverage industries where selective disconnection is vital and where an integral safety technology exists, such as a safety PLC or similar system.The ESX10-T combines purely electronic trip characteristics and active current limitation to allow selective disconnection of loads connected to 24 VDC power supplies. Selective load protection prevents complete shutdown of the system by quickly disconnecting the faulty path when an overload or short circuit occurs.Active current limitation allows the ESX10-T to respond much faster to overload or short circuit conditions than the power supply. It limits the highest possible current to 1.3 to 1.8 times the rated the capacity and is capable of switching on capacitive loads up to 20,000 uF - with disconnection only in the event of an overload or short circuit. Conventional protective elements cannot manage this as they either respond too slowly or are susceptible to nuisance tripping due to inrush currents.Upon detection of an overload or short circuit in the load circuit, the power-MOSFET switching output of the ESX10-T interrupts the current flow at 1.1 times rated current after 3 seconds. Failure and status indication are provided by a multi-colour LED and status output signal.The ESX10-T is 80.3 mm (2.76") high by 12.3 mm (0.5") wide and allows direct mounting on a 35 mm din rail consequently simplifying installation and saving cabinet space. It is available in fixed current ratings from 0.5 to 12A.www.e-t-a.ca
