Secondary Voltage: 42 V AC
Secondary Current: 1.5 A

Product Description

The Siemens 4AM3242-4TV00-0EA0 is a 63 VA SITAS transformer delivering 42 V AC at 1.5 A from a 230 V AC mains supply, dual-rated as both a safety isolating transformer (EN 61558-2-6) and a control transformer (EN 61558-2-2). The 42 V secondary sits within the SELV voltage band while providing higher drive capability for industrial control components.

Dual-Rating Advantage

EN 61558-2-6 safety isolating certification ensures galvanic separation suitable for SELV circuits
EN 61558-2-2 control transformer certification confirms suitability for contactor and relay loads
63 VA continuous with 190 VA S6 short-time rating handles high inrush inductive loads
230 V primary with ±5% tap selection (218/230/242 V) for precise output under varying mains conditions

Application Notes

The 42 V secondary is a common control voltage in markets where 24 V is insufficient for longer cable runs or higher-power solenoids, while still maintaining SELV safety status. Mounts via screws or DIN rail. Requires installation within an IP-rated enclosure. For a 24 V secondary option in the same power class, the 4AM3242-4TN00-0EA0 provides identical ratings with a 24 V output.
