Overview

The 3RV10 and 3RV13 molded case motor starter protectors for up to 800 A are compact, current-limiting motor starter protectors which can be used above all in motor feeders for special voltages of 440 V, 480 V, 550 V and 690 V. They are used for switching and protecting induction motors and other loads with rated currents up to 800 A.

Note:

For motor feeders above 100 A, the 3VL molded case circuit breakers must be used for 400 V and 500 V, see "Building Technologies" в†’ "Low-voltage power distribution and electrical installation technology" в†’ "SENTRON protection, switching, measuring and monitoring devices" в†’ "Protection Devices" в†’ "Molded Case Circuit Breakers".

Type of construction

The molded case motor starter protectors are available in four widths:

• 3RV1353 – width 90 mm,
  max. rated current 32 A,
  at 550 V AC suitable for induction motors up to 22 kW
• 3RV1.6. – width 105 mm,
  max. rated current 250 A,
  at 690 V AC suitable for induction motors up to 160 kW
• 3RV1.7. – width 140 mm,
  max. rated current 630 A,
  at 690 V AC suitable for induction motors up to 315 kW
• 3RV1.83 – width 210 mm,
  max. rated current 800 A,
  at 690 V AC suitable for induction motors up to 500 kW

The 3RV1 molded case motor starter protectors for up to 800 A can be mounted in horizontal, vertical or lying arrangement directly on a mounting plate or mounting rail. Their rated data are not adversely affected as a result.

The phase barriers for better insulation between the phases are included in the scope of supply, and it is essential to use them.

The motor starter protectors can be supplied through top and bottom terminals without impairing their function, enabling them to be installed in any type of switchgear without any further steps.

Connection method

The 3RV1 molded case motor starter protectors for up to 800 A are suitable solely for screw connection.
