RXBA 4 is a static, three-phase relay that detects fuse failures by comparing the voltages on both sides of the fuse in each phase.

RXEDA 1 is a microprocessor based time-overvoltage relay.

RXETB 1 operates in case of fuse failure in one or two phases of a three-phase system or if the voltage in one phase drops below 40 % of rated voltage and the other two phases have rated voltage.

The compact current relay RXHB 411 has a wide application range as an important part of the backup protection for feeders and lines, transformers, capacitor banks, electric boilers as well as for generators and motors.

The four overcurrent and earth-fault relays RAHL/RXHL 401, 411, 421 and 422 are intended for power system applications and as backup to e.g. the 650 or 670 series terminals at all system voltage levels including EHV.

RXIB 24 is a static, high-speed ac overcurrent relay generally used where high-speed and consistent operate and reset times are required.

The current measuring relay type RXIG is a static, instantaneous ac current relay which can be used as over- or undercurrent protection.

RXEDK 2H is a microprocessor based time-over/undervoltage relay with two measuring stages, which are switchable for over- or undervoltage functions independently of each other.
