LV Toroidal Transformers - CT/CTD1 
Super Immune: Our relays are specially designed to work in environments with extreme electrical noise, providing signal immunity to interferences such as frequency. This helps avoiding false alarms and unnecessary stops.
 
Enhanced Security: The enhanced security feature is a backup metering channel. An alarm is triggered to inform of the need for maintenance at the next halt.
 
Easy Maintenance: The equipment allows for testing without the need to stop any ongoing processes.
 
Small size of 22.5 mm.: The D30 relay is also known for its small size. It is ideal for manufacturers of MCC’s which have limited panel space.
 
Versatile: Positive or negative logic can be can be selected maiking the relay more flexible at use.

Description

The Earth Leakage Relay ELR-A is a device which offers a wide possibility of regulation both for time and current. The housing of the ELR-A is DIN six module size (one module is 17.5mm) together with the 28mm built-in toroidal transformer.

The Earth Leakage Relay ELR-T is a multirange device with adjustable delay time and sensitivity. Suitable for direct pulse current. Immune to external disturbances. Sensitivity from 0,025 to 25A. Trip time delay from 0,02 to 5s. Compact device. Suitable for motor control centers (MCC).

The Earth Leakage Relay ELR-T is a multirange device with adjustable delay time and sensitivity. Suitable for direct pulse current. Immune to external disturbances. Sensitivity from 0,025 to 25A. Trip time delay from 0,02 to 5s. Compact device. Suitable for motor control centers (MCC).

The Earth Leakage Relay ELR-B type is suitable for application where very reduced dimensions are necessary. The relay allows to easily select the tripping current value (0.3A or 0.5A) and tripping delay time (0.02s or 0.5s).

The Earth Leakage Relay ELR-3C type is particularly suitable for application where very reduced dimensions are necessary. Although of very reduced dimensions (3 modules of 17,5mm), the relay is featured by a very wide either current or delay setting field.

Earth Leakage Protection WITHOUT built-in toroidal suitable for Motor Control Centers (MCC) and electrical distribution boards and control panels in general.

Electronic relays with automatic reclosing up to 3 attempts with defined (1 m) or adjustable (1 to 60 s) time.

Electronic relays with automatic reclosing up to 3 attempts with defined (1 m) or adjustable (1 to 60 s) time.

The toroidal transformer is installed between the source and the load. The system works on the current balance principle. In a correct installation the vector sum of the currents is zero and the relay will not trip.
