Description
Type XR relay has been developed for specific applications, and
suitable for use with type AR relay range. It is an
electro-mechanical relay with a consistent positive action, a
long service life and complying with the appropriate requirements
of IEC 60255. The XR351 has three attracted armature elements.
It incorporates a time delay on de-energisation, to keep the
relay in an operated condition, during temporary reduction in
the battery voltage.
Applications
• Supervision and ensuring the integrity of the trip circuit of a
breaker
• Continuous supervision, during both, open and closed
position of circuit breaker
• Preclosing supervision to prevent circuit breaker from being
closed where the trip relay has not been reset
• Rated voltage
• Contact arrangement
• Case style and size

These resistors are supplied loose with the relays for
non-drawout case. It is important to ensure that the resistors
are correctly connected.
