BPM600UL Equivalent & Substitute Parts

Part Overview

The BPM600UL is a 347 V, 40 kA transient voltage suppressor varistor manufactured by Eaton - Bussmann Electrical Division. This single-circuit DIN rail module with plug-in terminal block is designed for transient overvoltage protection in electrical systems rated up to 600 V AC. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BPM600UL is determined by the following critical parameters:

• Mounting Type: DIN Rail compatibility is mandatory for direct replacement in existing installations
• Package Configuration: Module with plug-in terminal block interface
• Voltage Rating: System voltage compatibility (600 V AC maximum)
• Surge Current Capacity: Minimum 40 kA handling capability
• Circuit Count: Single-circuit configuration for the primary application
• Operating Temperature Range: Functional performance within -40°C to 80°C

The BPMA550UL is identified as a substitute part within the Eaton - Bussmann product family. However, this substitute exhibits differences in circuit count (3 circuits versus 1 circuit), maximum AC voltage rating (1.1 kV versus 600 V), and operating temperature range (-35°C ~ 85°C versus -40°C ~ 80°C). These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The BPMA550UL is an active product from the same manufacturer, providing continuity within the Eaton - Bussmann Electrical Division product line. The substitute part carries RoHS compliance certification, whereas the original BPM600UL does not specify RoHS status. Both parts share DIN Rail mounting compatibility and are classified under the same transient voltage suppressor category.

Selection of the BPMA550UL as a substitute requires evaluation of the following factors:

• The substitute operates at a higher maximum AC voltage rating (1.1 kV versus 600 V), which is compatible with 600 V system applications
• The substitute provides three circuits compared to the single circuit of the original part
• The substitute operates across a slightly wider temperature range (-35°C ~ 85°C versus -40°C ~ 80°C)
• The substitute is currently in active production status, ensuring availability and supply chain continuity

Frequently Asked Questions (FAQ)

Q: Can the BPMA550UL directly replace the BPM600UL in a 600 V AC system?

A: Both parts are DIN Rail mounted transient voltage suppressors from Eaton - Bussmann. The BPMA550UL has a higher voltage rating (1.1 kV), which is compatible with 600 V applications. However, the BPMA550UL provides three circuits versus the single circuit of the BPM600UL. Application-specific circuit requirements must be evaluated.

Q: What is the significance of the circuit count difference?

A: The BPM600UL is a single-circuit module, while the BPMA550UL is a three-circuit module. Circuit count determines the number of independent protection channels. System design must accommodate the multi-circuit configuration of the substitute.

Q: Are there compatibility concerns with the plug-in terminal block interface?

A: Both parts use DIN Rail mounting. The BPM600UL specifies a plug-in terminal block package, while the BPMA550UL is described as a DIN Rail module. Terminal block compatibility with existing installation infrastructure must be confirmed.

Q: Does the operating temperature range difference affect substitution?

A: The BPMA550UL operates from -35°C to 85°C, while the BPM600UL operates from -40°C to 80°C. The substitute has a lower minimum temperature limit (-35°C versus -40°C) and a higher maximum limit (85°C versus 80°C). Applications requiring operation below -35°C may not be suitable for the substitute.

Q: What is the significance of RoHS compliance on the BPMA550UL?

A: The BPMA550UL carries RoHS compliance certification, indicating conformance to Restriction of Hazardous Substances regulations. The original BPM600UL does not specify RoHS status. RoHS compliance may be a requirement for certain applications or markets.
