Bently Nevada 177313‑02‑02‑00 Proximitor Sensor Spare Parts In Stock

　　I. Product Overview

The Bently Nevada 177313‑02‑02‑00 is a single-pole, thermal-magnetic miniature circuit breaker from the 1489-M series. Featuring a C-curve trip characteristic and a 20A rated current, it is designed to provide overload and short-circuit protection for branch circuits in industrial control cabinets. The product complies with UL489 and IEC industrial standards and is designed for standard DIN rail mounting. It protects power supply circuits for PLCs, servo drives, instrumentation, and control cabinets, making it suitable for both new projects and spare part replacements (please contact us to verify current stock availability).

　　II. Product Advantages and Features

1. Dual thermal-magnetic protection: The thermal element handles overload protection, while the magnetic element rapidly interrupts short-circuit faults to safeguard downstream control components.

2. C-curve tripping characteristic: Suitable for standard resistive and mildly inductive loads; it accommodates the brief inrush currents associated with equipment startup without nuisance tripping.

3. Reversible line/load connection: Power supply and load terminals are non-directional, allowing for flexible and convenient cabinet wiring.

4. Dual-purpose terminals: Supports installation with either cables or copper busbars, accommodating various internal wiring configurations.

5. Excellent shock and vibration resistance: Ideal for industrial environments with significant vibration, such as factory automation and machinery applications.

6. Current-limiting capability: Rapidly limits fault current during a short-circuit event, reducing the risk of damage to downstream components caused by high-current surges.

7. Status-indicating handle: Clearly distinguishes between ON, OFF, and tripped positions, facilitating on-site troubleshooting.

8. Standard 35mm DIN rail snap-on mounting: Simple installation and removal without special tools, ensuring high efficiency when replacing spare parts within the cabinet.

9. Multiple certifications: Holds UL, CSA, and IEC certifications, ensuring compliance for use in projects both domestically and internationally.

　　IV. Functional Description

The Bently Nevada 177313‑02‑02‑00 provides two main functions: circuit overload protection and short-circuit protection. In the event of a sustained circuit overload, the thermal element heats up and triggers a delayed trip to disconnect the circuit. If a short-circuit fault occurs, the magnetic tripping mechanism trips instantaneously to cut off power, preventing cable burnout and damage to downstream equipment such as PLCs and instruments. The handle allows for manual switching (ON/OFF) and serves as a circuit disconnector during maintenance. After a fault trip, the handle remains in a middle position; power can be restored by manually resetting the handle to the ON position. This device does not include earth leakage protection; an earth leakage accessory is required for that function.

　　V. Application Scenarios

Protection for PLC control cabinet power circuits, servo drive auxiliary power circuits, instrument power supply protection, automation assembly line electrical cabinets, control cabinets for packaging and textile machinery, HVAC electrical control boxes, equipment compliant with North American standards, replacement parts for imported equipment, and branch circuit protection for factory automation equipment.

　　VI. Selection Recommendations

1. Full model number Bently Nevada 177313‑02‑02‑00: “M1” indicates 1-pole, “C” indicates C-curve tripping, and “200” indicates 20A. Do not confuse this with other models in the same series (e.g., 10A, 13A, 25A); they are not directly interchangeable. 2. The C-curve model is suitable for standard resistive and slightly inductive loads; for motor loads with high starting inrush currents, the D-trip series is recommended.

3. This model is single-pole only and disconnects the live wire; for DC applications, ensure the voltage does not exceed 48V.

4. Install inside a control cabinet; do not expose directly to the outdoors. Adequate cabinet protection is required for environments with high humidity or dust.

5. Verify certification requirements during selection; for projects exporting to North America, prioritize the version with UL489 certification.
