Circuit breaker Rittal SV 3431.000 — 690 V, 100 A, 89 × 141.5 mm

Rittal SV 3431.000 is a compact circuit breaker designed for industrial and commercial switchgear. Rated for operation up to 690 V and a nominal current of 100 A, this unit provides overcurrent protection and circuit isolation while fitting into distribution panels and control cabinets with limited space. Its form factor, 89 mm wide by 141.5 mm high, allows straightforward integration into modular assemblies and retrofit applications.

Advantages

The circuit breaker combines a high voltage rating with a 100 A nominal current capacity in a compact footprint, enabling reliable protection without occupying excessive panel space. Its standardized dimensions and mounting profile simplify installation and replacement in existing systems. The device is designed to perform consistent overcurrent interruption and to support safe isolation of circuits during maintenance or fault conditions.

How to use

Select appropriate wiring and protection coordination according to system voltage and fault current levels. Mount the breaker in the panel using the recommended mounting profile and secure electrical connections with correctly sized conductors and torque settings. Verify correct phase connection and perform insulation and continuity checks before energizing. Use the breaker’s switching and tripping functions to isolate circuits for maintenance and to protect against overloads and short circuits.

Recommendations

Ensure the breaker is specified to match the system voltage and prospective short-circuit current. Follow local electrical codes and the enclosure manufacturer’s instructions when installing into control cabinets or distribution panels. Periodically inspect connections and the breaker for signs of wear, overheating, or mechanical damage, and test trip operation as part of routine maintenance.
