Siemens Monitoring Relay 1 NO/1 NC 16A 1.6 A F.L.C 1A Contact Rating 2.5 W 24V AC/DC 3RR2241-1FA30

Siemens 3RR2241-1FA30 monitoring relay 1 NO/1 NC is a high-quality electrical automation component designed for robust load monitoring applications in industrial environments. It is ideal for monitoring current values on motors or other AC loads within 2 or 3 phases, detecting overcurrent, undercurrent, phase failure, or wire breaks.

This relay supports a control and supply voltage of 24V AC/DC and has an adjustable current range from 1.6 to 16 amperes, providing versatile protection for motors rated at 16A with a 1.6 A full load current (FLC). The device features a 1 normally open (NO) and 1 normally closed (NC) contact configuration, offering reliability in switching and signaling operations with a 1 amp relay contact current rating.

The monitoring relay includes both automatic and manual reset methods with screw terminal connections ensuring secure electrical contact. Its compact size with dimensions 79mm length, 45mm width, and 81mm depth allows easy mounting directly onto 3RT2 contactors, specifically suitable for contactor sizes S00 or S0. The relay's IP20 rating ensures protection against solid foreign objects, making it suitable for indoor industrial use.

Engineered to meet multiple international standards - IEC 60947-1, IEC 60664, IEC 60068-2-27, UL, CE, CSA, CCC, and EAC approvals - this Siemens relay assures high reliability and safety compliance in demanding manufacturing, industrial automation, electrical control panels, and HVAC systems.

Application scenarios include motor load monitoring, alarm and warning for phase failure, current blocking, phase sequence faults, and wire break detection, making it an essential component for enhancing motor system protection and operational safety.
