Kollmorgen B-604-C-A1-B2
Overview:
The B-604-C-A1-B2 is a fully specified variant of the B-604 braking resistor with two configuration modifiers: “A1” denotes a specific mounting/mechanical option (e.g., particular bracket or flange style), and “B2” denotes a specific electrical connection option (e.g., different terminal block or lead style). This is a custom-ordered part number for OEMs requiring a non-standard mechanical or electrical interface while retaining the core B-604 electrical performance.

Structural Features:
- Base construction identical to standard B-604 series
- A1 mounting option may include: specific hole pattern, DIN-rail clip, or angled bracket
- B2 terminal option may include: quick-disconnect terminals, different wire gauge leads, or alternative connector type
- All configurations maintain the same thermal performance and electrical ratings
Working Principle:
Identical to all B-604 series resistors. Regenerative energy from motor deceleration is routed through the resistor by the servo drive’s braking transistor, converting kinetic energy to thermal energy dissipated via the aluminum housing.
Advantages:
- Custom mechanical/electrical interface without redesigning the resistor core
- Same proven reliability and thermal performance as standard B-604
- Reduces OEM design effort — Kollmorgen handles configuration
Applicable Industries:
Same as B-604 series — any application requiring dynamic braking with custom mounting/wiring.
Installation Requirements:
- Follow A1 mounting drawing for bolt pattern and torque specifications
- Follow B2 wiring diagram for correct terminal connection
- Maintain 100 mm airflow clearance
Usage Precautions:
- Verify A1/B2 configuration matches the physical part received before installation
- Do not substitute A1 or B2 variants — they are not electrically interchangeable
- Same thermal precautions as all B-604 resistors apply
