SIRIUS 3RV1011-1KA15 Circuit Breaker Overview

The SIRIUS 3RV1011-1KA15 is a versatile circuit breaker, optimized for motor protection. As a product under the esteemed SIRIUS brand, its key focus is on ensuring smooth operation and safety for motor circuits.

Design & Specification:

This circuit breaker carries the product designation of "3RV1" and is crafted specifically for motor protection applications. It belongs to the size S00 category, ensuring compatibility with contactors of the same size (S00). Additionally, there's an option to extend its capabilities through an auxiliary switch.

Technical Data:

For performance, the breaker has a power loss of 9.25 W at AC in the hot operating state, and 3.1 W per pole in similar conditions. It possesses an insulation voltage rated at 690 V under a degree of pollution 3 and a surge voltage resistance of 6 kV. With an impressive mechanical service life of 100,000 operating cycles, both for main and auxiliary contacts, it boasts an electrical endurance of 100,000 cycles. This breaker is also designed to function optimally up to an altitude of 2,000 meters above sea level and operates effectively within an ambient temperature range of -20°C to +60°C.

Main Circuit Features:

The main circuit has 3 poles and an adjustable current response value of 9 to 12.5 A. Operational voltages range from 20 to 690 V, with the rated value at AC-3 and AC-3e being 690 V. The operational current rated value stands at 12 A, and the operational power varies based on voltage, peaking at 7.5 kW for 690 V at AC-3 and AC-3e.

Auxiliary Circuit Attributes:

The auxiliary circuit is transverse in design. It features 1 NC and 1 NO contact for auxiliary actions. The operational current for auxiliary contacts at AC-15 ranges between 0.5 A to 2 A, depending on the voltage, while at DC-13, it varies from 0.15 A to 1 A.

Protection & Monitoring:

Safety remains paramount with phase failure detection, a trip class of CLASS 10, and thermal design for overload release. It also showcases impressive short-circuit breaking capacities with values ranging from 2 kA to 100 kA based on the voltage. The breaker's short-circuit protection leans on its magnetic trip design and requires specific fuse links for optimal protection.

Mounting & Installation:

The breaker's flexibility is evident in its mounting capabilities. It's suitable for screw and snap-on mounting onto a 35mm DIN rail, per DIN EN 60715 standards. Dimension-wise, it stands at 90mm in height, 45mm in width, and 75mm in depth.

Connections & Terminals:

The main current circuit employs screw-type terminals, accommodating a variety of conductor cross-sections. Auxiliary contacts also cater to a range of conductor types. The tightening torque for both main and auxiliary contacts is between 0.8 to 1.2 N·m, with a Pozidriv size 2 screwdriver tip being the optimal tool for adjustments.

Safety Metrics:

Safety is pivotal. With a protection class IP20 on the front according to IEC 60529, the breaker ensures finger-safe touch protection, further solidified by its rocker switch display version for clear switching status visibility.

In conclusion, the SIRIUS 3RV1011-1KA15 is a testament to precision engineering, balancing performance, safety, and versatility. Whether it's motor protection or ensuring operational efficiency, this circuit breaker is a reliable choice for various industrial applications.
