ECSR400

ECSR400 is an electronic circuit shield retarder (ECSR) type fuse designed for motors and motor-driven loads. The ECSR400 fuse has a nominal rating of 401A and a interrupting rating of 10kA, making it suitable for 3-phase systems of up to 600Vac and barring currents up to 16kA. The fuse can be used in either standard or current-limiting applications.

The ECSR400 is designed for use in motors that have protection systems that are designed to reduce damage caused by short-circuit, overload and no-load conditions. The fuse trips instantly on the detection of an overcurrent or overload condition, reducing the time to interruption and, thus, preventing damage to sensitive electrical components.

The ECSR400 has a dual sensing element. One element senses the actual current flowing through the circuit while the other element senses the rate of change of the current. The dual sensing element allows the ECSR400 to react faster than competing fuses, providing superior protection against short circuits, overloads or no-loads. The ECSR400 also complies with UL 4248A requirements and is UL listed.

The ECSR400 fuse functions as an effective protective device in motor hazardous applications. The fuse is designed to open quickly in the event of an overload or short circuit, thus ensuring the safety of personnel and equipment and preventing damage to property. The fuse also limits the flow of current and provides protection from current overload.

The fuse is designed to open quickly if an overload occurs, thus preventing damage to motors and other motor-driven equipment. The fuse also limits the flow of current through the circuit during normal operation and limits the current in the event of a short circuit. In addition, the fuse limits voltage in the event of a high voltage fault, thus protecting other motor and motor-driven equipment.

The ECSR400 also features a protective coating which helps protect the fuse from moisture and salts. This helps to protect the fuse from corrosion and corrosion induced failure. The fuse is designed to ensure that it can withstand the effects of lightning strikes. The ECSR400 also features an integrated cylinder which contains the fuse element, allowing for easy installation.

The ECSR400 fuse is suitable for a wide range of applications, including motor hazardous locations, AC motor starters, circuit breakers, overcurrent protective devices, diverters and isolation switches. The fuse is also suitable for applications that have an operating temperature range of -20°C to +85°C and a current rating of 401A. The fuse also complies with UL 4248A requirements and is UL listed.
