E-T-A obtains Class I, Div 2 Group A, B, C, D certification for ESX0-T trip

E-T-A obtains  Class I, Div 2  Group A, B, C, D certification for ESX0-T trip
September 18, 2008 - E-T-A Circuit Breakers announces the ESX10-T Electronic Circuit Protector now has Class I, Division 2 - Group A, B, C and D, UL 1604 certification. The remarkably compact device combines purely electronic trip characteristics and active current limitation to allow selective disconnection of loads connected to 24VDC 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 capacity and is capable of switching on capacitive loads up to 20,000 µF - 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 multicolor LED and status output signal.

Specifications and Approvals
ESX10-T Electronic Circuit Protector is just 2.76 inches high by 0.5 inch wide and allows direct mounting on a 35 mm din rail consequently simplifying installation and saving cabinet space. The ESX10-T is approved to UL 2367 as a “Solid State Overcurrent Protector” and is available in fixed current ratings from 0.5 – 12A. UL 1604 certified; Class I, Division 2, Group A, B, C, and D.

Applications
Typical applications for the ESX10-T include Automation systems (e.g., machine tool, packaging machines) and Process control systems (Petro/Chemical, Pharmaceutical, Food and Beverage, etc.) where selective disconnection is vital and an integral safety technology exists, such as a safety PLC or a similar system.

Availability
Type ESX10-T Electronic Circuit Protector is available from stock.
