Auxiliary Relays, Timers and Latching Relays
TAX relay
Auxiliary relays do not perform protective functions themselves but add additional logical functions to protection systems when combined with protection and measurement relays. 
CEE can offer a range of auxiliary relays including those that are designed to fit in the standard modular cases ("R-case") or products for mounting within control panels.

R-Case Relays
Auxiliary DC power supply for circuit breakers and protection relays, powered from line CTs

Do you need to convert a 24VDC supply to 48VDC?  Consider the CTC7000.
Trip and Lock-out relays with either manual reset (RAD 7000 series) or electrical reset (RADE7010).  These products are also used in conjunction with protection relays that have output contacts which are too weak to operate a circuit breaker trip coil.
