3RV1011-1CA10 Circuit-Breaker: An In-depth Overview

General Overview:

Belonging to the renowned SIRIUS product line, the 3RV1011-1CA10 is a circuit-breaker designed for motor protection with size S00. It has three poles for the main current circuit, ensuring the comprehensive safety and functionality of connected devices.

Core Functionalities:

While this circuit breaker does not have a removable terminal for auxiliary and control circuits, it excels in providing overload protection and recognizing phase disturbances. However, it doesn't come with functionalities such as short-circuit-to-earth recognition, an auxiliary switch, an under-voltage release mechanism, or a trip indicator in its default configuration.

Product Extensions:

The circuit breaker's design allows for the inclusion of an auxiliary switch if required by the user. However, there's no provision for a motor drive as an optional extension.

Technical Specifications:

The 3RV1011-1CA10 boasts an impressive impulse voltage resistance of 6,000 V. It ensures user safety with its IP20 protection class on the front, coupled with a finger-safe design. The unit can be safely installed at altitudes up to 2,000 meters above sea level. Durability is a key feature of this circuit breaker, with its ability to withstand shocks of 25g for 11 milliseconds. Environmentally adaptable, it can withstand temperatures ranging from -50°C to +80°C during transport and storage, and -20°C to +60°C during operations. The device has a typical active power loss of 6W.

Main Circuit Features:

This circuit breaker can operate at a voltage of up to 690V. Its service power at AC-3 at 400V is rated at 0.75kW, and the operating current at AC-3 at 400V has a rated value of 2.5A. In terms of durability and reliability, the main contacts can endure up to 100,000 mechanical operating cycles. Moreover, the frequency of operation with AC-3 is at a maximum of 15 times an hour.

Auxiliary Circuit Details:

The auxiliary circuit does not feature changeover contacts.

Protection Features:

Classified under the CLASS 10 trip class, this circuit breaker has an adjustable response current for the current-dependent overload release ranging between 1.8A and 2.5A.

Installation and Dimensions:

For installation flexibility, it supports both screw and snap-on mounting methods, specifically onto a 35mm standard mounting rail as per DIN EN 50022. It can be mounted in any position, ensuring adaptability to various setups. Dimensionally, the device measures 81mm in depth, 90mm in height, and 45mm in width.

Connection Details:

The main current circuit connectors are conveniently located on the front side of the device. The electrical connections for both the main current circuit and the auxiliary and control current circuit are designed as screw-type terminals. As for the connectable conductor cross-section, the circuit-breaker supports:

• Solid conductors: 2x (0.5 ... 1.5 mm²) and 2x (0.75 ... 2.5 mm²)
• Finely stranded conductors with conductor end processing: 2x (0.5 ... 1.5 mm²) and 2x (0.75 ... 2.5 mm²)
• Stranded conductors: 2x (0.5 ... 1.5 mm²) and 2x (0.75 ... 2.5 mm²)

In conclusion, the 3RV1011-1CA10 from the SIRIUS product line is a robust and versatile circuit breaker designed with motor protection in mind. Users and integrators are encouraged to refer to official Siemens documentation or consult experts for a comprehensive understanding and safe installation.
