How to Select and Install

1. Identify System Requirements: Determine voltage (AC/DC, value), continuous current, number of poles needed (refer to a 2 pole circuit breaker definition if unsure), and fault current level.
2. Choose the Correct Model: Select from our RSB1 (higher voltage, single-pole) or B3 series (DC, multi-pole) based on your technical specs.
3. Plan the Panel Layout: Use our dimensional drawings to plan integration into your panel, considering clearances and wiring paths as you would for any hydraulic power unit wiring diagram.
4. Safe Installation: De-energize the panel. Mount the breaker securely and connect wires to the correct terminals with proper torque.
5. Verification & Testing: Energize the system and test the manual trip/reset function. For critical systems, a calibrated overload test is recommended to verify the hydraulic operating mechanism of circuit breaker performs as specified.

FAQ

Q1: What is a hydraulic-magnetic circuit breaker and how does it work?

A1: It combines magnetic force with a hydraulic delay. During an overload or short circuit, the magnetic field pulls a plunger. The plunger moves through a viscous fluid, providing a precise time delay before tripping, making it stable across temperature ranges.

Q2: Can I use the 250V AC/DC rated RSB1 model in a pure 80VDC system?

A2: Yes. A breaker rated for 250V AC/DC is suitable for use in lower voltage DC systems (like 80VDC). The voltage rating indicates the maximum it can withstand. Always ensure the current rating is also appropriate.

Q3: When should I choose a 3-pole breaker over multiple single-pole breakers?

A3: A hydraulic circuit 80 dc 3-pole breaker is used when you need to simultaneously disconnect multiple related DC conductors (e.g., in a 3-wire DC system). It ensures complete isolation and is often more compact and easier to wire than three separate single-pole units, as shown in a 4 pole circuit breaker wiring diagram (conceptually similar for 3 poles).

Q4: Are these breakers suitable for protecting a 12v dc hydraulic power unit?

A4: Absolutely. Our DC-rated B3 series breakers (e.g., 80VDC 100A model) are ideal for protecting the power input to a 12v dc hydraulic power unit. You must select a breaker with a current rating matching or slightly above the pump's maximum draw.

Q5: Do you provide technical drawings for panel design?

A5: Yes, upon request, we can provide detailed dimensional drawings and terminal diagrams to assist your engineers in panel layout and creating accurate wiring diagrams.
