1SVR730841R1200 ABB Control Industrial Automation Components

ABB 1SVR730841R1200 is a current monitoring relay designed for single-phase under-/over-current monitoring with a SPDT (Single Pole Double Throw) - 1C/O contact type. It features a housing speed of IP50 and terminal speed of IP20. The communication protocol is specified at 85.6 mm, with a net height of 4 kV and a rated impulse voltage (Uimp) of 22.5 mm. It offers protection functions at 600 V and a rated insulation voltage (Ui) of 103.7 mm. The control voltage operates on a DIN rail with normally closed (NC) auxiliary contacts accommodating various wire sizes and types, including flexible and rigid wires ranging from 0.5-4mm2 and 18-12AWG. It supports a supply voltage of (AC) 220-240 V and is designed for 100,000 operations, with the contacts made from a Silver-Nickel alloy (Ag / Ni) for enhanced durability up to 30,000,000 operations. The net width is indicated by a green LED for control/supply voltage presence, a red LED for overcurrent/undercurrent, and a yellow LED for output relay energization. The trip unit type is screw-clamp with a control circuit rated current of 4 A at 230Vac for AC-12, 3 A at 230Vac for AC-15, and 4 A at 24Vdc for DC-12, with a short circuit current breaking capacity (Icn) and protection settings designed for various current ranges including 3-30mA, 10-100mA, and 0.1-1A. The operating temperature ranges from -20°C to +60°C, accommodating a wide range of environmental conditions.
