Choosing electrical distribution switchgear protection is a matching exercise: the protective device has to line up with the current rating, the mounting style, and the level of assembly you actually need. In this Square D lineup, you're weighing four very different products: a compact 20A bolt-on circuit breaker, a 70A three-pole I-line breaker, a high-current power distribution block, and a complete MCC bucket. The listed prices range from $27.69 to $1,613.61, which makes the decision about matching the component to the job, not just about the sticker price.
Quick take
- Least expensive listing: Square D EHB14020 Circuit Breaker at $27.69
- Most expensive listing: Square D 8998 Model 6 MCC Bucket at $1,613.61
- For 70A three-pole industrial protection: Square D BDA36070 at $269.99
- For high-current distribution: Square D 9080 LBA-365202-1 at $172.69

Product notes
Square D EHB14020 Circuit Breaker, 20A, 1 Pole, 277V, Type EHB, Bolt-On
At $27.69, this is the least expensive protection component in the group. It's a 20A single-pole breaker with bolt-on mounting, rated for 277V, and listed as new with a black finish and a trip indicator. That makes it a straightforward fit for commercial and industrial panels where the bus pattern matches EHB bolt-on breakers. The trade-off is the single-pole, 20A envelope; if your load needs three-pole interruption or a higher current, this breaker won't do it. It's the right buy when you need a small branch-circuit breaker now and the rest of the system already matches EHB dimensions.
NEW Square D 9080 LBA-365202-1 Power Distribution Block 760A CU/620A AL 600V NNB
This $172.69 power distribution block is listed as new open box, with a United States origin, and it's built for high-current distribution rather than interruption. The title shows a 760A copper and 620A aluminum rating at 600V, which makes it the highest-amperage product in this set by a clear margin. The trade-off is that it is a distribution block, not a circuit breaker; it gives you a terminal point to split power to multiple circuits, but it won't provide the trip function of the EHB14020 or BDA36070. Choose it when your switchgear needs a rated distribution point for heavy feeders.
Square D BDA36070, 70amp 3 pole I-line circuit breaker BD70 Powerpact, 70A
The $269.99 BDA36070 is the only three-pole breaker in this comparison. It's listed as new open box and specified for industrial use, with an I-line connection on the line and lugs on the load side, thermal interruption, instantaneous break time, and a 551-600V AC rating. If your panel uses I-line buses and you need to protect a 70A load, this is the direct protective component. The limitation is the 61-70A rating and the I-line mounting pattern; it doesn't bolt on like the EHB14020, and it's below the current range of the power distribution block. That makes it the middle option for a specific feeder application.
Square D 8998 Model 6 MCC Bucket PowerPact HJ030 8536SCO3H612S
At $1,613.61, this MCC bucket is a complete assembled unit, not a stand-alone breaker. The title and description position it as a 12-inch bucket with a PowerPact HJ030 and a SPEED-D switch style, and it's listed as new. This is the product to consider when you're building or replacing a motor control center bucket and want the full assembly coordinated in one package. The trade-off is the price and the scope: you're paying for the entire bucket, so retrofitting a single breaker in an existing panel would be overkill. If your project calls for a complete MCC bucket, this gives you the integrated unit.
Final recommendation by use case
- Need a 20A branch-circuit protective device? The Square D EHB14020 at $27.69 delivers bolt-on, single-pole protection.
- Need a 70A three-pole industrial breaker? The Square D BDA36070 at $269.99 provides 70A, three-pole interruption with I-line mounting.
- Need to split high-current feeders? The Square D 9080 LBA-365202-1 at $172.69 handles 760A copper / 620A aluminum and works as a distribution point.
- Need an integrated MCC bucket? The Square D 8998 Model 6 MCC Bucket at $1,613.61 is the complete unit for that job.
