Comparing the 17.5MM Relays

	THREE-PHASE MONITOR RELAYS (PXE)	ALTERNATING RELAYS (AE1)	VOLTAGE MONITOR RELAY (VXE)	TIME DELAY RELAYS (TE5 & TE6)
Primary function	Phase monitoring	Load alternation	Voltage monitoring	Time-based control
Choose it when…	You need to detect three-phase fault conditions	You need to balance runtime across redundant loads	You need to detect operation outside a voltage range	You need a dedicated timing function and range
Typical applications	Pumps, compressors and three-phase motors	Redundant pumps and compressors	Voltage-sensitive equipment and control panels	Timed sequences and process control
Key difference	Phase-condition protection	Alternates operating sequence	Single-phase AC or DC monitoring	Simple, function-specific setup
