Siemens Circuit breaker for transformer protection, size S00, 286A Part number 3RV2411-4AA10

Product Overview

The Siemens 3RV2411-4AA10 is a SIRIUS 3RV2-series circuit breaker (size S00) designed for transformer protection, system protection, and short-circuit / overload protection of motor-feeder or general low-voltage circuits. It is a compact, screw-terminal protected breaker with adjustable thermal-magnetic release and built-in breaking capacity for industrial and distribution applications.

Key Features

• Circuit breaker, size S00 (compact size for space-efficient panel installation)
• Adjustable A-release (thermal/magnetic trip) setting: 10 … 16 A
• Suitable for transformer protection, system protection, short-circuit protection or motor feeder protection
• Screw-terminal connections for reliable and vibration-resistant wiring
• Standard breaking capacity — capable of high short-circuit currents
• Compact width — easy integration into distribution boards or control panels
• Versatile use: transformer circuits, feeder circuits, starter combinations, or general power protection
• Mountable on standard 35 mm DIN rail (or screw mounting) — flexible installation

Applications

The 3RV2411-4AA10 is ideal for use in power distribution boards, motor-feeder circuits, transformer circuits, sub-distribution panels, and industrial control cabinets requiring reliable short-circuit, overload, and transformer protection. Typical applications include protection of small transformers, feeder lines, motor starter combinations, and general branch-line protection in industrial or commercial electrical installations. Its compact S00 size and DIN-rail mounting make it especially useful where space is limited or modular installation is preferred.
