Allen Bradley 1336-CAP-SP15A DC Bus Capacitor Assembly

FAQ

Q1: What is the Allen-Bradley 1336-CAP-SP15A used for?
A: The 1336-CAP-SP15A is a DC bus capacitor assembly used inside Allen-Bradley 1336 drives to store electrical energy and smooth DC bus voltage for reliable motor control operation.

Q2: Which drives are compatible with the 1336-CAP-SP15A?
A: It is designed for Allen-Bradley 1336STEF Frame F drives with a 460V class power system, including compatible 1336 PLUS, PLUS II, FORCE, IMPACT, and REGEN drive platforms.

Q3: What are the main specifications of the capacitor?
A: The capacitor assembly has a capacitance of 4600 µF and is rated for a 400 VDC capacitor voltage application.

Q4: Is the 1336-CAP-SP15A a complete variable frequency drive?
A: No. It is only a replacement DC bus capacitor component installed inside compatible Allen-Bradley 1336 drive units.

Q5: What symptoms may indicate a failed DC bus capacitor?
A: Common signs include unstable DC bus voltage, drive faults, increased electrical noise, reduced performance, capacitor leakage, swelling, or visible physical damage.

Q6: What are the dimensions and weight of the 1336-CAP-SP15A?
A: The approximate dimensions are 160 × 90 × 90 mm, and the weight is approximately 0.91 kg. Actual values may vary slightly depending on manufacturing revision and packaging.

Q7: Can the 1336-CAP-SP15A replace another capacitor assembly?
A: Replacement should only be performed after confirming the drive model, frame size, voltage rating, capacitance value, mounting method, and original part number.

Q8: What should be checked before installing the 1336-CAP-SP15A?
A: Verify the drive model compatibility, disconnect and discharge the DC bus voltage completely, inspect terminals and mounting hardware, and follow proper electrical safety procedures before replacing the capacitor assembly.
